2 claims.

The invention relates to a cup or receptacle of the stacking type, where for shipment, storage, dispensing or other purposes, a plurality of similar cups or receptacles are nested one within another, and the primary object of the invention is to provide a simple and practical construction which will prevent adjacent cups or receptacles from wedging tightly together when in nested relation, and accurately determine the spacing of successive cups in the stack. In the drawingy Fig. 1 is a side view of a cup constructed in accordance with the invention.

Fig. 2 isv a central vertical section through the cup shownI in Fig. 1.

Fig. 3 is a view similarto Fig. 2 but showing two such cups in nested relation.

Fig. 4 is a Iplan view lookingflfror'nfthe top of Fig. 1.

n il f The side .walls [fof lthe icupor' ep outwardly toward "its mouth 2, xwliere y f 4av plurality of-suehpups 'may be nested'one`-witliin the other, and usually although not necessarily, the cup will be of circular crossisection. The cup may be constructed of molded paper pulp.

In order to prevent the flaring side walls of adjacent receptacles from wedging tightly together when nested into a stack, I provide the cup with a suitable number of inwardly extending abutments 3 located near but somewhat above its bottom, and which are positioned so as to engage under parts of a .second similarly constructed cup which are underneath the corresponding abutments of the second cup when the two cups are nested togetheras shownin Fig. 3. In the simple form of the invention mustrated the abutments 3 of the rst cup engage und`er the bottom wall 4 of the second cup. The abutments 3 of the lower cup shown in Fig. 3, accordingly engage the bottom wall 4 of the upper cup before the upper cup has penetrated far enough into the lower to wedge the two cups tightly together. In

1 other words," the internal shoulders 3 act as ance between the side walls I of the cups, and

(Cl. 22S-4.5)

by providing what may be termed fiat indentations 5, in the otherwise frustrofconical side walls of the cups, these indentations being somewhat triangular in form as viewed from the outside of the cup and merging into the circular outer edges of the bottom wall 4, the abutments 3 extending chord-like (as shown in Fig. 4) across the otherwise circular contour of the angular walls of the cups. It should be noted that the constructio'nal features above referred to provide internai transverse dimensions of the cup beneath the shelves 3, and at the level of the indentations 5, which are not greater than said internal dimensions (or diameter) at the level of shelves 3; thus the shelves 3 do not interfere with the operation of drawing the cup from a mold, and the indentations 5 furthermore support the shelves 3 adequately against bending or bulging. A suficient'number of these abutments 3 may be provided to insure that each cup will rest firmly on-the abutments of the cup next underneath, and without requiring any special angular relation'or fitting -of the cups with respect to their common central longitudinal axis.

While the invention has been described as embodied in a particular construction, it should be understood that changes may be made therein without departing from its principle, within the scope of the appended claims.

I claim:

1. A one piece paper cup of the stacking type having its body portion flaring outwardly toward the mouth of the cup whereby a plurality of such cups may be Anested one within another, said body portion being of substantially circular cross section, and the side wall of the cup near its bottom being provided with a plurality of internal substantially horizontal chord-like shelves constructed to serve as stops engageable with the bottorn wall of a second similar cup when in nestedv relation to the first cup and thereby prevent the walls of the second cup from wedging tightly into the rst, thev aforesaid shelves being integrally joined lto the parts of the body of' the cup which lie therebeneath, by substantially plane and Vertically extending indented portions of the outer wall of the cupfsaid last mentioned portions being substantially triangular in shape.

2. A one piece molded cup of pulp-like material and of the stacking type, having its body portion flaring outwardly toward the mouth of the cup whereby a plurality of said cups may be nest ed one Within the other, the side walls of the cup near its bottom being provided with a plu-r rality of spaced internal substantially horizontal shelves projecting inwardly from the side Wall and constructed to serve as stops engageable with the bottom wall of a second similar cup when in nested relation to the rst cup and thereby pre- Vent the walls of the second cup from wedging tightly into the first, the aforesaid shelves being integrally joined to the parts of the body of the cup which lie therebeneath, by downwardly extending indented portions of the outer wall of the cup, the transverse internal dimensions of the cup underneath said shelves and at said indented portions being not greater than said dimensions at the level of the shelves.
